King's Highway 137 is a short spur
highway that connects Highway 401 to Interstate-81, via the Thousand Island
Bridge and Hill Island. North of the Thousand Islands Parkway, Highway
137 is a freeway; South, it is a conventional 2-lane highway. Highway 137
was not affected by provincial downloading. Before late 2005, or early
2006, Highway 137 had been an un-posted designation. Since that time
however, the MTO has surprisingly done an about face on that subject and has
started indicating Highway 137 both along its route, and at its interchanges.
Unfortunately, all of this new signage for Highway 137 has meant less signage
for its continuation as Interstate 81 at the Highway 401 interchange, leaving a
rather confusing situation for motorists.
